Description

Electronic weft selecting system

The utility model relates to the loom servicing unit, particularly about the improvement to the loom weft selector.

Existing loom divides two big classes, and a class is a fly-shuttle loom, and another kind of is shuttleless loom.Fly-shuttle loom has the branch of one-sided single box, multiple box on one side and multiple box on both sides; Shuttleless loom then has looms such as water spray, jet, projectile shuttle and arrow shaft not.Now that the weft selector brief introduction of two class looms is as follows:

Fly-shuttle loom is an example with the multiple box on one side fly-shuttle loom, and its weft selector is made up of select latitude signal sense station, crank mechanism, mechanical translation device and the multi-shuttle box operating mechanism of jacquard.Jacquard reads from the eyelet of line version and selects the latitude signal, three bent axles are done corresponding upper and lower displacement, to select the latitude signal to be delivered to the mechanical translation device, after decoding, machinery amplify, produce a mechanical control action and drive the multi-shuttle box operating mechanism, handle a plurality of shuttle box arrays that are stacked in a plane, at race one end, move with race is vertical, when certain shuttle box was moved to the race plan-position, the shuttle in this shuttle box was chosen as into latitude.The weft selector of nearly all fly-shuttle loom all adopts this structure.But the weft selector of this structure, because inertia mass is bigger, during the lifting of shuttle box array, inertia force is very big, body elastic vibration fierceness can influence the functional reliability of loom and the raising of the loom speed of a motor vehicle; Since after in a single day this class loom is in certain circulation and selects the latitude state, just relatively fixing, desire the original circulation of conversion, must change the change-box gear, mechanical parameters such as cam, very inconvenient; Owing to select the latitude signal from the line version, and the programming of line version, punching, processing are very time-consuming, very uneconomical.
